Determine whether each pair of angles is a pair of vertical angles, a linear pair of angles, or neither. Select the correct answer for each lettered part.

Answers

A)  ∠AFC and ∠CFD are neither. They share more than a vertex, so they are not vertical angles. Also, they do not form a straight line so they do not make a linear pair.
B)  ∠AFB and ∠CFD are neither. Vertical angles are also known as vertically opposite angles. While these two only share a vertex, they are not opposite each other. They also do not form a linear pair, as they do not form a straight line.
C)  ∠BFD and ∠AFE are vertical angles. They are opposite each other and share only a vertex.

Answer:

Linear Pair, Neither, Vertical.

A bag contains 3 red marbles and 4 blue marbles.A marble is taken out from the bag and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the bag are the same colour.

Answers

A bag contains 3 red marbles and 4 blue marbles. a marble is taken at random and replaced. Another marble is taken from the bag. Work out the probability that the two marbles taken from the bag are the same color.

Total number of marbles in the bag is 3 + 4 = 7.The problem asks for the probability of (RR) or (BB).It's worthy to note we are replacing the balls after each draw, which means we always have 7 to draw fromSince each draw is independent, we take the product of each event for the total event probability.

P(RR) = 3/7 * 3/7 = 9/49
P(BB) = 4/7 * 4/7 = 16/49

We want to know P(RR) + P(BB)
P(RR) + P(BB) = 9/49 + 16/49 = 25/49

I think 2/7 would be the probability

What is the equation of the line that is perpendicular to the line and passes through the point (6, 2)?

Answers

Hey there! :D

So, when you find something perpendicular, you are finding the opposite reciprocal.

The slope is 1/2 because:

y=mx+b <== it is in this form; m is equal to slope.

Flip the 2 and 1 and make it negative.

2/1= -2

We already know "C" and "D" aren't the options. Now, we can just plug in the points given to see if it works. Plug in the set of points (6,2)

y=-2x+14

2=-2(6)+14

2=-12+14

2=2 <== this works. This is our answer. Let's just make sure by checking the other one.

y=-2x-2

2=-2(6)-2

2=-12-2

2=-14 <== that is not true.

The first option is correct.

Option 1---------> salary=$600 per week
Option 2---------> salary=$350+$256=$606 per week
Option 2> Option 1
then
she will earn more money with the option 2

the answer part A) is option 2

Part B)
If x represents Chloe’s weekly sales
equation option 1---------> 600
equation option 2---------> 350+0.08*x

the equation can be used to determine which option will benefit her the most is making the two options equal
600= 350+0.08*x

the answer Part B) is 600= 350+0.08*x

Part C)
she will earn more money with Option 1 when
600 > 350+0.08*x------------> (600-350) > 0.08*x-------> 250 > 0.08*x

El Generico public high school got a new flag pole. But they completely forgot to buy a cord and NO ONE knows how tall the flagpole is! To find out, they decided to use similar figures! As the sun was setting, Bob the janoitor set up a 5-foot stick next to the flagpole and compared shadows. The 5 foot stick cast an 8-foot shadow. The shadow of the flagpole was 32-feet long.

Use rules of similar polygons to figure out how tall the flagpole is! HINT: this will involve proportions!

Answers

if two figures or lengths are similar, then the ratios of the corresponding lengths are equal.
Thus, 8/32 =5/x

A dad has two daughters – wendy and julia. wendy is twice as old as julia. the man is now five times as old as wendy, and in 4 years he will be six times as old as julia. find the present age of the father.

Answers

x = age of julia
2x = age of Wendy
10x = age of dad (because dad is five times as old as Wendy)
(x+4)*6=10x+4 (because in four years, that's why I added 4 to both sides, dad's age will be now 10x+4 and Julia's age x+4, now dad is 6 times as old and I multiplied Julia's age by six) ==> 6x+24=10x+4, now subtract 4 from both sides:
6x+20=10x, let's subtract 6x from both sides
20=4x ==> x=5
because age of father is 10x, we substitute x value and we get

Lou Harris is guaranteed a minimum $275 weekly salary plus 5.25% of his total sales. What were his total sales for a week in which his gross pay was $700?

Answers

so he had a gross of $700, now 700 - 275 is 425, since 275 is what his weekly salary is, then the 425 is the 5.25% from the sales.

let's say "x" is the total amount for the sales, namely the 100%, but we also know that 5.25% of that is 425, the leftover from the 700 bucks minus his salary, what is "x" anyway?

Describe how you would estimate the square root of a number that is not a perfect square without using a calculator. lets say n was the imperfect square number and the square root is w. the square root of n = n+w squared/ 2w.

Answers

To get the square root of imperfect square we can use the formula , which is usually accurate to about two decimal places,
√X =√S +(X-S)2√S
Where, X = the number you want the square roof of, and S is the closest square you know to x.
For example 75 is an imperfect square
Thus, X=75 and thus the nearest number S = 81, this ,means √81 =9.
Putting this into the formula;
√75= 9+(75-81)/2/2(9)
= 9 + -6/18
= 9-0.33333 = 8.667
= 8.667, thus the square root of 75 is 8.66

ANSWER: 43% increased change

Hope this helps! :)

The approximate percentage of change will be 43.24%.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

An antique car was purchased for $7400 and is not worth $10,600.

Then the approximate percent of change will be given as,

P = [(10600 - 7400) / 7400] x 100

P = (3200 / 7400) x 100

P = 0.4324 x 100

P = 43.24%

The approximate percentage of change will be 43.24%.

Hello there! I can help you! A degree in a polynomial is the highest exponent out of the terms in that polynomial. For example, the degree for 3x³ + 2x² - 7 is 3, because that is the highest valued exponent. Let's solve each of these questions.

1. Okay, so there are 3 terms in the polynomial, which makes it a trinomial. That eliminates A, C, and D, because those answers do not say trinomials. The degree in the trinomial is 2, because that's the highest exponent in any of the terms. That is a quadratic trinomial. The answer is B.

2. Alright. So like the previous question, there are 3 terms in the polynomial. That eliminates answer choices C and D. The degree is 3, which makes it cubic. This is a cubic trinomial. The answer is A.

3. The degree is as stated above, the highest exponent in the polynomial out of the terms. 2 and 4 are not the degrees in this polynomial, so those answers are crossed out. It seems like the degree is 5. However, there is a monomial where two exponent amounts are together. In this case, we will combine the exponents by adding. 2 + 4 is 6. There. The degree is 6. The answer is D.

Note: Keep in mind that linear is where the highest degree is 1, quadratic is where the highest degree si 2, cubic is where the highest degree is 3, quartic is where the highest degree is 4, quintic is where the highest degree is 5. Quadratic and Quartic are not the same, and are easy to get mixed up due to the spelling. Be careful not to make an error on which is which, when it comes to those two.

Answers

Zeros are the x values which make the function equal to zero. Set it up as you would for a binomial with a constant multiplier "k" to account for the y-intercept (0, -5) given.

f(x) = k(x-2)(x-3)(x-5)

Use the y-intercept (0,-5) to solve for k.

-5 = k(0-2)(0-3)(0-5)
-5 = -30k
-5/-30 = k
1/6 = k

The cubic polynomial function is then ..

f(x) = (1/6)(x-2)(x-3)(x-5)

Linear factors are the linear (line) expressions you can factor out of the polynomial. They are (x-2), (x-3) and (x-5).

Given :

A cubic polynomial whose zeroes are (2 , 0), (3 , 0), and (5 , 0).Cubic polynomial equation passes through (0 , -5).

Arithmetic operations can be used to determine the cubic polynomial equation. The generalised cubic polynomial equation is given by:

[tex]y = K(x-a)(x-b)(x-c)[/tex]

Where, K is constant and a, b, and c are the zeroes of the cubic polynomial equation. Therefore, the value of a, b, and c are 2, 3, and 5 respectively.

[tex]y = K(x-2)(x-3)(x-5)[/tex] ----- (1)

It is given that cubic polynomial equation passes through (0 , -5). So, put x = 0 and y = -5 in equation (1) to evaluate the value of K.
